Correct Answer: B

Rationale: Secondary amenorrhea refers to the absence of menstruation for 3-6 months in a woman who previously had regular menstrual cycles. In this case, Jean's lack of menstruation after giving birth and while breastfeeding her child for 6 months likely indicates secondary amenorrhea. This temporary suppression of ovulation and menstruation commonly occurs during breastfeeding due to the high levels of the hormone prolactin, which is responsible for milk production and can inhibit ovulation and menstruation. It is a natural phenomenon known as lactational amenorrhea. Once breastfeeding decreases or stops, menstruation usually resumes within a few months.

Correct Answer: B

Rationale: An ABI value less than 0.9 is indicative of mild peripheral arterial disease (PAD). In this case, an ABI of 0.85 falls below the 0.9 threshold, suggesting diminished blood flow to the lower extremities due to PAD. An ABI of 1.1 (Choice A) is actually elevated and not indicative of PAD. Values of 0.65 (Choice C) and 0.35 (Choice D) are significantly lower and would be consistent with moderate to severe PAD, rather than mild.

Correct Answer: C

Rationale: It is recommended for women to conduct breast self-examination immediately prior to their menses. This is because the breasts are less likely to be tender, lumpy, or swollen during this time of the menstrual cycle, making it easier to detect any abnormalities such as lumps or changes in the breast tissue. Conducting breast self-examination around this time each month can help women become familiar with the normal look and feel of their breasts, making it easier to detect any changes that may indicate a potential issue.

Correct Answer: C

Rationale: Lateral epicondylitis, commonly known as tennis elbow, is a condition characterized by pain and tenderness on the lateral (outside) aspect of the elbow. It is typically caused by overuse or repetitive strain of the extensor muscles in the forearm, leading to inflammation of the tendons attached to the lateral epicondyle of the humerus.

Correct Answer: B

Rationale: A condylar joint is a type of synovial joint that allows movement in two planes, typically flexion/extension and abduction/adduction. The interphalangeal joints of the hand, which are the joints between the phalanges (finger bones), exhibit this type of movement, making them an example of a condylar joint. The hip joint (choice A) is a ball-and-socket joint, the temporomandibular joint (choice C) is a hinge joint, and the intervertebral joint (choice D) is a cartilaginous joint, none of which are examples of condylar joints.
